TECHNICAL FIELD

BACKGROUND

With the emergence of smart phones in recent years, the demand for miniature camera lens is increasing day by day, but in general the photosensitive devices of camera lens are nothing more than a charge coupled device (CCD) or a complementary metal-oxide semiconductor sensor (CMOS sensor). As the progress of the semiconductor manufacturing technology makes the pixel size of the photosensitive devices become smaller, and the current development trend of electronic products towards better functions and thinner and smaller dimensions, miniature camera lens with good imaging quality therefor has become a mainstream in the market.

In order to obtain better imaging quality, the lens that is traditionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure. While, with the development of technology and the increase of the diverse demands of users, and as the pixel area of photosensitive devices is becoming smaller and smaller and the requirement of the system on the imaging quality is improving constantly, the five-piece lens structure gradually appears in lens design. The five-piece lens has good optical performance, but the design on focal power, lens spacing and lens shape is not reasonable, thus the lens structure could not meet the requirements for having a large aperture, a wide angle and ultra-thinness while having good optical performance.

Therefore, it is necessary to provide a camera lens which meets the requirements for having a large aperture, ultra-thinness and a wide angle while having good optical performance.
